The flow cells contain a special silica glass window and compartments to insert optical couplers, which attach to the fiber optic cables from the photometer. The flow cells can also be used with PendoTECH’s Flow Cell Stand with integral couplers in place of the optical couplers to connect the fiber optic cables. -

NOTE: The fiber optic cables must be secured so they are not free to move around, be stepped on, leaned against, or otherwise damaged during normal operations. The minimum bend radius for fibers UV PM2 Photometer is 8” (20.3cm). Only hand tighten SMA-905 connections. Never use a wrench, pliers, or other tool. Over-... -

Connect the power and ground to the system. For laboratory systems, a 24VDC power brick is included with every PM2. However, the global use wall plug(s) must be ordered separately. For panel-mounted systems, a 13-position terminal block connector is on the back of the PM2. Use a small flathead screwdriver to loosen the screw, insert a NON-ENGERGIZED 12-48VDC lead (with the end stripped so the metal wire is exposed) to position 9, and tighten the screw to secure the lead. -
Page 13: Led-Based Absorbance
The LED is located internal to the photometer and is specific to the application. Therefore, the PM2 UV photometer is a dedicated instrument for monitoring only one or two specific analytes of interest. Shown below are three example LED spectrum profiles graphs for typical LED light source wavelengths 260/280/300/880nm (Figures 5-8). -

In brief, the photometer works as follows: The measuring system is in the detector block of the photometer. Light is provided by an LED, which produces a stable light output at a narrow wavelength range. -
